I5 is a generally L shaped member to which thebracket I1 is fastened and it is itself carried by a bracket member Iewhich is fastened to the back A1 of the housing base by means of screwsI2; I8 is a magnet coil having a core I. It is mounted in the bracket I5in general opposition to the enlarged member or boss I1 which isfastened to the fork I1.

J is a member upwardly extending from the base A. It may be formed as alug integral with the base. Attached to it is a generally L shapedmember 1 which carries a magnet coil J2 provided with a core J3. J 1 isa boss or enlarged member attached to a lever J5 which lever ispivotally mounted at J 5 in a bracket J2 which is itself fastened to theL shaped member J1. Pivotally mounted at the outer or free end of thelever J5 is a dog J2. J9 is a lug extending from one end of the baseportion of the dog. J1 is a spring fastened at one end of the lug J11and at the other to the bracket J11 which extends outwardly and isfastened at its lower end to the member J1. J 12 is a stop pin fastenedto the member J11 and adapted to limit upward movement of the lever J5.The spring normally holds ythe lever in the position shown particularlyin Figure 6, thereby holding the dog J 2 out of engagement with theratchet wheel G2. J14 is a stop pin mounted in the bracket part G5 andadapted to limit counterclockwise movement of the dog. J 15 is anadditional stop pin mounted also in the part G1 and adapted to limitdownward movement of the dog. When the magnet J2 is energized, the leverJ5 is drawn in a clock-wise direction, causing the dog to engage theteeth of the ratchet Wheel G8 and turning it in a counter-clockwisedirection. This movement is limited by contact of the dog with thelimiting pin J 15. Since the ring G11 and the enlarged surface G1oattached to the segment G9 are all mounted upon the sleeve G2 whichmoves with the ratchet wheel G8, this assembly ofparts is given motionand this motion is controlled and limited by the mechanism justdescribed.

K is a bracket mounted upon the base A provided with a laterally bentupper portion K1 upon which is mounted a generally L shaped member K2and magnet K3 having a core K1. K5 is a laterally enlarged membermounted on the lever K6. The lever K6 is which is itself journaled inupwardly extending lugs K8 which in the form here shown form part of thebracket member K1 which is fastened to the base A.

K23 is a stop pin mounted on the lever portion K12and adapted to limit the clock-wise movement of the lever K12. In oneposition the notch K16 and the lever K engage the pin K12 of the dogK12. -This position of engagement is shown in Figures 2 and 6. K24 is aleaf spring which is mounted beneath the lever K2, and

the lever.

normally holds it upward in the position shown in Figure 2. When themagnet K2 is energized, it raises the right end of the lever K2 as shownin Figure 2 and correspondingly moves down the portion K12 of Thisdownward movement is limited by the lug K30 which as here shown isformed integrally with the base portion A. When the lever K, K12 ismoved so as to draw downward' the end K12 the lever K15 moves with itand' since it is in engagement with the pin K1' on the pawl K12, itmoves the latter out of engagement with the ratchet teeth K19 on thering G14; This movement is shown in dotted lines in Figure 12. Whenthedog K12 is moved out offengagement with the ratchet teeth, the ring G14is then free to move and the spring G2xs which is wound by the shaft Grethereupon rotates the ring G14 and the segment G2 in the directionindicated by the arrows in Figure 12. One of the pins the curved uppersurface K2e of the leverK, and tends to move causing the dog to returnto its normal position in engagement with the ratchet teeth-K11" y Themovement of the lever K1 in response to rotation of the ring G14and-contact with the y pin K2s is limited by a stop member- K2? which ismounted on the lever portion K12. .Attached to, and in this case, formedintegrally with, the lever K, isan upwardly projecting lug K211 uponwhich is pivotally mounted a pawl L.'

It is evident that while I have shown and described a practical workingembodiment of my invention, many changes might be made inproportion,size and relation of parts without departing from the spirit of myinvention, and I wish my description and drawings therefore to be takenas in a broad sense diagrammatic, and not as limit= ing me to thelspecific forms described and shown.

The use and operation of my invention are as follows.

The use and operation may best be followed from an examination ofFigure, 13

which is a wiringcdiagram. As shown in that ligure there are twostations designated generally by the letters X and Y. The operatioifoftransmission between the two is as follows: Assuming that the operatorat station X wishes to send a-message to the central station he iirstpushes down the starting button D2 thereby bringing the pring leaves E2and E2 and leaves E2 and 2 into contact with each other. This closes thespring leaves E2 and E10 and establishes a circuit from the battery athrough the wires a1 a2 and the spring leaves E11-E12 and wire a2 to thetime printing magnet R8 through the wires a1 a back to the battery. Theoperator then dials, -for example number 9 on the indexing unit which isdesignated on the wiring diagram as X2 while still pressing down thestarting button D2. By rotating the dialing disc in a clock-wisedirection, the lever X5 moves out of contact with lever X2, and allowingthe spring levers X2 X7 to come into contact. The dialing disc is thenallowed to return to its starting or at rest position and the cam X2 isthus rotated and closes the spring leaves X2 X12. This, takes place asoften as the number dialed. When this action takes place a contact ismade and a circuit established from the battery a throu h the Wires a1a2 b, spring leaves E2 and Eg2, the spring leaves X2 X12 of the indeXingdial X2 through the spring leaves E7 and E2, the wire 1 and the paperfeed magnet c2 of the substation X, thence through the wire 62 a5 backto the battery. Another circuit is established from the battery athrough the wire a1 and b, the spring leaves 2, E2, leaves X2 X10 andspring leaves E11 E7 through the wires b1 b1 and the paper feed magnetk2 of the central station vY, the wires b2 a5 back to the battery.

The operation of the dial is lcontinued after the pressure is releasedfrom the starting button. The turning of the dial closes a circuit fromthe battery a through the wires a1 a2 and b, the spring leaves .E2 E1contact springs X2, X", spring leaves E2, E2 the wire b1, the paper feedmagnet k2, wires b2 a5 back to the battery. Another circuit from thewire b1 through the wire b4, paper feed magnet k2 of the central stationY, the Wires b5 a5 back to the battery.

Rotation of the cam X8 closes a circuit from the battery a through thewires a1 c, contact pins 101 upon the segment G2, spring leave c, wire401, relay magnet 82, wire c2, spring leave E2 and E7, contact springsX2,

Y -1-5 and thereby establishes a clrcuit l X10 of the dial X2, thespring leaves E, E, wire c3, spring leave H. contact pins k", wires c*and a5 back to the battery. Another circuit is established from thebattery a through the lwires al, c, the contact pins' k1 and the leafspring c, the wires c1 c5, relay magnet S2 of the central station Y Thewires c", c2, the spring leaves E8 and E7, contact springs X9 and X10,spring leaves E3 and lt, Wires c3, spring leave' H, contact pins 705,wires c4 and a5 back to the battery.

The magnetizing of the relay magnets S2 szrauses the attached sprinleaves to close from the the wires al, d, printing the wire d1 thespring and back to the battery a through wheel magnet 7'2, leaves se, s,wires d2, b2 a battery.

Another circuit is established from vthe battery a through the wire dspring leaves S8, 12, wire dT printing wheel magnet J2 ofv the centralstation Y, thence through the wires (Z8 a5 and back to the battery.

The operation of the circuits above described is used when it is desiredtoprint numerals, that is to say, to transmit numerals and it will beunderstood that in the opthe main station so eration as above described,a message 1s sent from the sub station X to the central station Y and innormal operation at each station the message is printed and a record isthus made of the message sent.

If it is desired to send letters instead of numerals this may be done bypressing the shift button F of the substation and thereb a circuit isclosed from the batterya througii the wires al f, switch leaves f1, f2,wire f3, the shift magnet 10,the wires f, d2, b2, a5 and back toethebattery.' Another circuit is made from the battery a through the wiresa1 f, switch leaves f1, f?, wire f, shift magnet Il of the centralstation Y through the wires f7, a back tothe battery. Y

It will' be understood that in the two stations, that isthe onedesignated as the sub station and the one designated as the centralstation, 'the sending and recording' mechanisms are normally identicaland thus a message may be sent in either` direction where, for example,the apparatus is installed in a factory, a central station is in theoffice, sub stations may be established at a variety of placesthroughout the factory, for example, the actory. The operator of themachine desiring supplies or mechanical assistance, for example, willoperate his sub-station and his message will'be recorded at his substation, the hour, time and date beingautomatif cally recorded and hismessage being at the same time recorded inl 4conjunction with the dateand time stamped. At the same time that this record is made at hissubstation an identical message and record is produced at that there isat the oilice up and refuses to function,

'prises a series at several different machines in;

information of what he wants and a record of the .fact that he asked forit with the time of a particular sort in my drawings, still many othertypes of printing mechanisms might be used and for some purposes it isdesirable to use record making mechanism which em- I ployes no ink; onesuch form is that in which increments, letters or other stamps areimpressed upon the paper and create in effect an embossing. y

It will be noticed that in each dialing assembly alternating contactpoints such as K1 and G21, as shown in Figure 13, are of dl'erentpolarity. This is done as a precaution so that if for any reason notmove in harmony, one of the circuits will n'o dead and it will benecessary to commence ialing from the beginning again. l

The segment Gr9 may be referred to as a commutation type switch and itwill be noted that the segments are so' relatedmechanically that theymove in unison and the wiring circuits are so disposed that when thecircuit is closed on one of the commutation switches through positivebattery, it is closed on the other switch through negative battery andvice-versa; and as the switches move from point to point in unison, eachswitch steps from positive to negative and vice-versa. If for any reasonthe commutation switches get out of step and-we have both switches onpositive or both on negative, immediately theapparatus controlled by theswitches ties thereby preventing improper operation.

It will be further not/ed that the transmis;A sion of signals betweenthe two systems is eil'ected by a continuous series of impulses Vasdistinguished from `interrupted impulses or from intermittent impulses.

Discrimination between signals is effected by the numerical number in aseries of impulses. For instance, the impulse used intransmittingsignals in my apparatus com# of opening and closing of thecircuit. An impulse consists, for instance, of a closing of the circuitfor 'f-G of a second and an opening for To transmit the letter C forinstance, three impulses will be given, taking a of a second becauseeach impulse lasts ,16 of a second.' During each of these impulses thecircuit will be closed 7 100 of a second and open/lOO of a second. Theseare nominal values selected for example only.
